一、單作(zuo)用葉(xie)片(pian)泵(beng)的工作(zuo)原理(li)： ATOS葉(xie)片(pian)(pian)泵(beng)由(you)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)(zi)1、定(ding)子(zi)(zi)(zi)(zi)(zi)(zi)2、葉(xie)片(pian)(pian)3、配(pei)(pei)油(you)盤(pan)和端蓋等(deng)部件所組成(cheng)。定(ding)子(zi)(zi)(zi)(zi)(zi)(zi)的(de)(de)內表面是圓柱形孔。轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)(zi)和定(ding)子(zi)(zi)(zi)(zi)(zi)(zi)之間(jian)存在(zai)著(zhu)偏(pian)心(xin)(xin)。葉(xie)片(pian)(pian)在(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)(zi)的(de)(de)槽內可(ke)靈活滑動，在(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)動時(shi)的(de)(de)離心(xin)(xin)力以及通入(ru)(ru)葉(xie)片(pian)(pian)根(gen)部壓(ya)力油(you)的(de)(de)作(zuo)用(yong)下，葉(xie)片(pian)(pian)頂部貼緊在(zai)定(ding)子(zi)(zi)(zi)(zi)(zi)(zi)內表面上(shang)，于(yu)是兩(liang)相鄰葉(xie)片(pian)(pian)、配(pei)(pei)油(you)盤(pan)、定(ding)子(zi)(zi)(zi)(zi)(zi)(zi)和轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)(zi)間(jian)便形成(cheng)了(le)一個個密封的(de)(de)工(gong)作(zuo)腔。當(dang)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)(zi)按逆時(shi)針方向旋轉(zhuan)(zhuan)(zhuan)(zhuan)時(shi)，圖右側的(de)(de)葉(xie)片(pian)(pian)向外(wai)伸出，密封工(gong)作(zuo)腔容積(ji)逐(zhu)漸增大，產生真空，于(yu)是通過(guo)吸(xi)(xi)油(you)口6和配(pei)(pei)油(you)盤(pan)5上(shang)窗(chuang)口將油(you)吸(xi)(xi)入(ru)(ru)。而(er)在(zai)圖的(de)(de)左側。葉(xie)片(pian)(pian)往里縮(suo)進，密封腔的(de)(de)容積(ji)逐(zhu)漸縮(suo)小(xiao)，密封腔中的(de)(de)油(you)液(ye)經配(pei)(pei)油(you)盤(pan)另一窗(chuang)口和壓(ya)油(you)口1被壓(ya)出而(er)輸出到系(xi)統中去。這種泵(beng)在(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)(zhuan)過(guo)程中，吸(xi)(xi)油(you)壓(ya)油(you)各(ge)一次，故稱單(dan)作(zuo)用(yong)泵(beng)。轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)(zi)受(shou)到徑向液(ye)壓(ya)不平(ping)衡作(zuo)用(yong)力，故又稱非平(ping)衡式泵(beng)，其軸承負載較大。改變(bian)定(ding)子(zi)(zi)(zi)(zi)(zi)(zi)和轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)(zi)間(jian)的(de)(de)偏(pian)心(xin)(xin)量(liang)，便可(ke)改變(bian)泵(beng)的(de)(de)排量(liang)，故這種泵(beng)都是變(bian)量(liang)泵(beng)。 二、雙作用葉片泵的工作原(yuan)理： ATOS葉片(pian)(pian)泵(beng)(beng)的(de)(de)作用(yong)原理(li)和(he)(he)單作用(yong)葉片(pian)(pian)泵(beng)(beng)相似，不同(tong)之處(chu)只在于定子(zi)(zi)(zi)表(biao)面是由兩(liang)(liang)段長半(ban)徑(jing)圓弧(hu)、兩(liang)(liang)段短半(ban)徑(jing)圓弧(hu)和(he)(he)四段過渡(du)曲線(xian)八個(ge)部分組成，且定子(zi)(zi)(zi)和(he)(he)轉(zhuan)子(zi)(zi)(zi)是同(tong)心的(de)(de)。在圖示轉(zhuan)子(zi)(zi)(zi)順時針(zhen)方(fang)向旋轉(zhuan)的(de)(de)情況下，密(mi)封(feng)工(gong)作腔的(de)(de)容(rong)積在左(zuo)上(shang)角(jiao)和(he)(he)右(you)(you)下角(jiao)處(chu)逐(zhu)漸(jian)增(zeng)大，為(wei)吸(xi)(xi)油區(qu)(qu)，在左(zuo)下角(jiao)和(he)(he)右(you)(you)上(shang)角(jiao)處(chu)逐(zhu)漸(jian)減(jian)小，為(wei)壓(ya)油區(qu)(qu)；吸(xi)(xi)油區(qu)(qu)和(he)(he)壓(ya)油區(qu)(qu)之間有一(yi)段封(feng)油區(qu)(qu)把它(ta)們隔(ge)開。這(zhe)種泵(beng)(beng)的(de)(de)轉(zhuan)子(zi)(zi)(zi)每轉(zhuan)一(yi)轉(zhuan)，每個(ge)密(mi)封(feng)工(gong)作腔完成吸(xi)(xi)油和(he)(he)壓(ya)油動(dong)作各兩(liang)(liang)次(ci)，所以稱為(wei)雙作用(yong)葉片(pian)(pian)泵(beng)(beng)。泵(beng)(beng)的(de)(de)兩(liang)(liang)個(ge)吸(xi)(xi)油區(qu)(qu)和(he)(he)兩(liang)(liang)個(ge)壓(ya)油區(qu)(qu)是徑(jing)向對稱的(de)(de)，作用(yong)在轉(zhuan)子(zi)(zi)(zi)上(shang)的(de)(de)液壓(ya)力徑(jing)向平衡(heng)，所以又稱為(wei)平衡(heng)式葉片(pian)(pian)泵(beng)(beng)。 雙作用葉(xie)片(pian)泵(beng)的瞬時(shi)流(liu)量是(shi)脈(mo)(mo)動的，當葉(xie)片(pian)數(shu)為4的倍數(shu)時(shi)脈(mo)(mo)動率小。為此(ci)，雙作用葉(xie)片(pian)泵(beng)的葉(xie)片(pian)數(shu)一般都取12或(huo)16。 意大利進口ATOS葉片泵部分型(xing)號： PFE-31028/1DV
